DL380 G7 SD Card slot - Can it be disabled?

See the subject...

Issue:

I am having trouble capturing and deploying a linux based OS on local hard drives and want to remove the SD card from the mix.

Removing the card is not an option going forward and am hoping there is a way to disable it in the bios. I have not found an option though. Is there an "Advanced" mode? or does anyone know how to disable it?
